| 摘 要： | 搭建生物质与废塑料共气化动力学模型，并用实验数据对其进行验证。选用6种生物质和聚丙烯作为共气化反应物，以水蒸气为气化剂，计算气化温度在300～1000℃之间、气化压强在0.1～0.8 MPa之间、聚丙烯和松木锯末质量比例在0.5～2.5之间，以及不同生物质类型等对生物质和聚丙烯共气化产气特性的影响。结果表明：松木锯末气化中添加聚丙烯后，最高产气量和最大产气速率增加，最高产气总流量提高21.46%，最高产气速率提高4.64%,H2和CO最高产量分别提高54.27%和79.51%；压强增加不利于提高共气化产气的H2和CO含量，有利于提高CH4含量；6种常见生物质和聚丙烯共气化产氢量大小顺序为：果皮>棉花秆≈玉米秸秆>杨树木屑>稻秆>条浒苔；聚丙烯掺混比率增加有利于提高H2、CO和CH4等组分产量。

| Abstract: | An kinetic model of biomass and polypropylene co-gasification was built, and the model was verified by experimental data, use six kinds of biomass and polypropylene as co-gasification reactants, steam as gasification agent. The effects of temperature between 300-1000 ℃, pressure between 0.1-0.8 MPa, mass ratio of polypropylene and pine sawdust between 0.5-2.5, and different biomass types on the co-gasification characteristics of biomass and polypropylene were calculated. After the addition of polypropylene in the gasification of pine sawdust, the maximum gas yield and maximum gas yield rate increased, the maximum total gas flow rate increased by 21.46%, the maximum gas yield rate increased by 4.64%, and the maximum H2 and CO yields increased by 54.27% and 79.51%, respectively. The increase of pressure is not conducive to the increase of H2 and CO content in co-gasification gas, but is beneficial to the increase of CH4 content. The order of H2 content from co-gasification of six types biomass and polypropylene is, peel > cotton stalk≈ corn straw>poplar sawdust>rice straw>Enteromorpha prolifera. It is beneficial to increase the yield of H2, CO and CH4 on increasing the blending ratio of polypropylene. |
